Frequently Asked Questions
What are casino wagering requirements?
Wagering requirements determine how many times you must play through a bonus before withdrawing. For example, 35x on €100 means you must wager €3,500. Lower wagering is better.
Are online casino games fair?
Licensed casinos use RNG (Random Number Generator) software certified by independent testing labs like eCOGRA, iTech Labs, or GLI. Check for certification seals and licensing info.
Can I play casino games on mobile?
Yes, most modern online casinos offer mobile-optimized websites or dedicated apps for iOS and Android. Games are designed with responsive layouts, and many casinos support instant play directly in your mobile browser without downloads.
How long do casino withdrawals take?
Withdrawal times vary by payment method and casino. E-wallets (PayPal, Skrill, Neteller) typically process in 24-48 hours, credit/debit cards take 3-5 business days, and bank transfers may take 5-7 days. First-time withdrawals may require identity verification (KYC).
